BuyThe story of Idaho Falls
Idaho Falls, the fourth most populous city in Idaho, serves as a central hub for commerce, culture, and healthcare across Eastern Idaho, extending its influence into parts of Wyoming and Montana. Situated along the Snake River, the city offers a blend of natural splendor and urban conveniences. The River Walk, a picturesque pathway tracing the Snake River, features running and bike trails, art installations, and points of interest, forming a focal point for community activity.
The city’s distinctive location makes it a gateway to some of the region’s most iconic natural wonders, including Yellowstone National Park and Grand Teton National Park. Whether exploring local attractions or venturing into the surrounding wilderness, Idaho Falls provides a convenient base for a variety of experiences.
From Taylor's Crossing to Eagle Rock
The area now known as Idaho Falls was initially inhabited by Native American tribes, including the Shoshone-Bannock and Northern Paiute, who utilized the Snake River for sustenance and travel. The city's modern origins trace back to 1864, when Matt Taylor constructed a timber-frame toll bridge across the Snake River, establishing a vital crossing point for westward travelers on the Montana Trail. This early settlement was known as Taylor's Crossing.
By 1866, the growing community was renamed Eagle Rock, inspired by a small island in the Snake River frequented by eagles. The arrival of the Utah and Northern Railway (U&NR) in 1879 further spurred the town's expansion, with the railroad constructing an 800-foot iron bridge across the river. This railway connection facilitated the influx of settlers to the Upper Snake River Valley, leading to the development of farms and irrigation canals that transformed the arid landscape into productive agricultural land.
The Birth of Idaho Falls and Agricultural Prosperity
In 1887, a significant portion of the railroad facilities relocated to Pocatello, causing a temporary dip in Eagle Rock's population. However, in 1891, town leaders were persuaded by marketers to change the city's name to Idaho Falls, a strategic move to suggest an abundance of water and attract further development. Despite the name, the iconic waterfalls that define the city today were not created until 1911, when a retaining wall for a hydroelectric power plant reshaped the river's rapids.
The construction of the Great Feeder, then the world's largest irrigation canal, in 1895, diverted water from the Snake River and was instrumental in converting vast tracts of desert into fertile farmland. This agricultural expansion led to the cultivation of crops like sugar beets, potatoes, peas, grains, and alfalfa, establishing the region as one of the most productive agricultural areas in the United States.
The Atomic Age and Modern Growth
Idaho Falls' history took a significant turn during World War II, as it became a center for nuclear research and development. The establishment of the National Reactor Testing Station (now Idaho National Laboratory) in 1949, located west of the city, marked a new era of scientific innovation. This facility achieved a historic milestone on December 20, 1951, by producing the first usable electricity from a nuclear reactor.
Today, Idaho Falls continues to flourish as a modern city with a population exceeding 64,000 as of the 2020 census. It maintains its role as a commercial and cultural center while embracing its unique history and proximity to natural wonders.
Begin your exploration of Idaho Falls with a walk along the River Walk, a multi-purpose trail system that follows the Snake River through the city. This scenic pathway is ideal for walking, running, or cycling, offering views of the namesake waterfalls and various art installations. For a deeper dive into local history and culture, visit the Museum of Idaho, which features exhibits on the state's past and often hosts special traveling displays.

Consider a visit to the Japanese Friendship Garden, situated on an island in the Snake River, which offers a serene atmosphere with traditional Japanese architecture and water features. For a unique outdoor experience, particularly during the warmer months, Heise Hot Springs, about 20 miles east of Idaho Falls, provides mineral pools, a water slide, and even a pizza parlor. Art enthusiasts can explore the Art Museum of Eastern Idaho or the ARTitorium on Broadway. The downtown area also offers a variety of shops, restaurants, and art galleries to discover.

Within the city, casual and comfortable clothing is recommended for most activities. A sweater or light jacket is advisable for early spring, fall, and even some summer evenings, as nighttime temperatures can be cool due to the desert plain location.
